SAN JOSE, Calif. (AP) — Disgraced Theranos CEO Elizabeth Holmes on Friday made what might be her final court appearance before beginning a 11-year prison sentence, unless a judge grants her request to remain free while her lawyers appeal her conviction for masterminding a blood-testing hoax.

The 90-minute hearing came four months after Holmes’ last court hearing. That was when U.S. District Judge Edward Davila sentenced her for duping investors in Theranos, a startup she founded 20 years ago and rode to fleeting fame and fortune on her promises of a revolutionary blood-testing technology.

Before the hearing started, a man in the audience in the San Jose, California, courtroom tried to approach the table where Holmes was sitting while carrying a document in his hand. He was quickly intercepted by security officers who forcibly removed him. Holmes didn’t appear flustered by the disruption.

The proceedings ended without a determination whether Holmes, 39, will be able to stay out of prison while her appeal unfolds or have surrender to authorities on April 27, as currently scheduled. Davila said he hopes to issue his ruling in early April.

The judge earlier this month used a last-minute legal maneuver to gain more time.

Holmes came to her St. Patrick’s Day hearing wearing a black blazer and blue skirt. She recently gave birth to her second child, according to court documents that didn’t disclose the gender or birth date.

One of her lawyers, Amy Saharia, argued that Holmes should be allowed to remain free because of various missteps in the presentation and omission of evidence during her four-month trial that make it likely an appeals court will overturn her conviction on four counts of fraud and conspiracy.

“We think the record is teeming with issues,” Saharia asserted. She specifically cited Davila’s refusal to allow the jury to see a sworn deposition that Balwani gave during a Securities and Exchange Commission investigation into Theranos’ downfall that Holmes’ defense team believes would have helped exonerate her.

Federal prosecutor Kelly Volkar countered there is “no likelihood for reversal” of Holmes’ conviction and asserted that the trial documented seven different categories of deception that she engaged in while running Theranos. Most of the deceit centered on a device dubbed “Edison” that Holmes had boasted would be able to scan for hundreds of diseases and other health problems with just a few drops of blood taken with a finger prick.

But the Edison produced such wildly unreliable results that Theranos began relying on third-party testing equipment already widely used on the market — a switch that Holmes concealed in an effort to keep the company afloat.

“That was shocking to investors,” Volkar reminded Davila.

The two opposing sides also sparred over how much restitution Holmes should pay defrauded investors whose trust briefly boosted her wealth to $4.5 billion based on Theranos’ peak value before its collapse.

Federal prosecutor Robert Leach argued her conviction for engineering a conspiracy justified restitution of nearly $900 million to repay Theranos investors swept up in her lies. “Just to apply common sense, the money these investors lost is the money they put in,” Leach said.

But Hollmes’ lawyer Patrick Looby countered that prosecutors were way off base by pursuing an “all or nothing” restitution amount. He noted that the jury in her trial couldn’t reach a verdict on three counts of investor fraud, prompting the prosecutor to dismiss those charges. At most, Looby contended, Holmes’ restitution penalty should be limited to the handful of investors who testified during her trial.
